Why is changing the filter so important? What filter should I use?

The filters keep the evaporator coils and the heat exchanger of an AC clean. These are essential parts of an AC, and they must be kept in proper condition. The evaporator is one of the main components of a heating and cooling system. It is located inside of the indoor fan section, and the filters are located just before it. First, the filter purifies the air and then it goes to the evaporator coil. The filters prevent the evaporator from getting plugged with dust. With the passage of time, the dust accumulates between the fins of the evaporator.

The accumulation of dust causes improper functioning of the evaporator coil which is not visible instantly but may take months to show up. The coil then restricts the airflow and reduces the efficiency of the system. Another problem that one might encounter because of dirty filters is ice build up. If your system didn’t show up with this problem in the past, then it might be because of the dirty filters. It is an indication that you are not changing your filters as often as required.
